OPERATIONAL

SUMMARY

I DECEMBER 1995 BROWNS FERRY 1 Unit 1 remains shutdown on administrative hold to resolve various TVA and NRC concerns. Unit 1 has been on administrative hold since June 1, 1985. As a result, TVA considers that accrual of reporting hours is suspended since the unit has a maximum dependable capacity of 0 MWe. Accordingly, TVA does not consider cumulative reporting period hours for the period beginning June 1, 1985, when calculating the operating status variables.

BROWNS FERRY 2 During the month Unit 2 operated at a capacity factor of 100 percent and generated 815,180 megawatt hours gross electrical power. As of December 31, 1995, Unit 2 has operated continuously for 133 days.

BROWNS FERRY 3 After being shutdown and on administrative hold since i June 1, 1985, the Unit 3 reactor was restarted and declared critical at 1203 hours0.0139 days <br />0.334 hours <br />0.00199 weeks <br />4.577415e-4 months <br /> on November 19, 1995. Power ascension testing was completed for Unit 3 on December 14, 1995. During the month Unit 3 operated at a capacity factor of 94.5 percent  !

and generated 766,410 megawatt hours gross electrical power. j As of December 31, 1995, Unit 3 has operated continuously for 33 days, a
